*Resistive Temperature Device (RTD)- Are temperature sensors that contain a sensing element whose resistance changes with temperature. These sensors are often placed so they can be in a position in the process where it can reach the same temperature. Platinum wire or films RTDs are the most common type in use today. Platinum RTDs are used to measure temperatures from -400 °F to 1550 °F. Due to higher accuracy and repeatability RTDs are slowly replacing the use of thermocouples in many industrial applications below 1200°F.

Two-Wire: Provides one connection to each end of the element. This construction is suitable where the resistance of the lead wire may be considered as an additive constant in the circuit, and particularly where the changes in lead resistance due to ambient temperature changes may be ignored. Three-Wire: Provides one connection to one end of the element and two to the other end of the element. Connected to an instrument designed to accept three-wire input, sufficient compensation is usually achieved for leadwire resistance and temperature change in Leadwire resistance. This is the most commonly used configuration. Four-Wire: Provides two connections to each end of the element to completely compensate for leadwire resistance and temperature change in lead wire resistance. This configuration is used where highly accurate temperature measurement is vital.

*Thermocouples- Thermocouples consist of two electrical conductors made of different metals that are joined at one end. Changes in temperature at the measurement junction induce a change in electromotive force (emf) between the other ends. There are two groups, the base metal thermocouples J, K, T, E and N and the precious metal thermocouples R, S, C and B. Each type has a characteristic (emf) vs. temperature curve and application range. The EMF curve is very dependent on the composition of each conductor. Type J and K are the most widely used in industrial applications. Type J (iron vs. copper-nickel (Constantan)) is versatile in that it can be used in both oxidizing and reducing atmospheres up to 1,400°F. Iron rusts at low temperatures where condensation can form. Type K (nickelchromium (Chromel) vs. nickel aluminum (Alumel) can be used up to 2,300°F in an oxidizing or inert atmosphere.

*Grounded vs. Ungrounded- A grounded junction places the junction in contact with the immediate case metal. In turn this allows for quicker response time. On the other hand, a tip that is grounded leaves it vulnerable to electromotive forces (EMF) in the environment, which potentially cause errors in the readings. An ungrounded junction is best suited when isolating the sensor is done and when response time is not a high priority.

*Performance- Ensuring exceptional performance of the sensor requires it to be in good thermal contact with the process at hand. When using both a sensor and thermowell together, a suitable heat transfer compound is needed to fill the gap between the sensor and bore of the thermowell. This in turn will improve the transfer of heat between the process and the sensor.

Sanitary Assemblies 3-A sanitary system accepted practices pertain to the sanitation aspects of equipment used to produce frozen desserts, egg, milk, cottage cheese, and similar food and dairy products. Included are Culinary Steam, Boiler Feed Water, Heat Exchangers, Transfer Station, Silo Tank, Atmospheric Pasteurizers, Pipeline Milking Systems and Feed Production. Why is 3A Sanitary Temperature Measurement Important? The following sanitary systems are dependent upon accurate temperature measurement; Pasteurization Systems include high temperature short time (HTST) at 105 degree's Celsius and higher heat shorter time (HHST) at 149 degree's Celsius. requirements. Boiler Feed Water Systems include temperature measurement to reduce water hardness and to prevent corrosion and scale in boilers and or to facilitate sludge removal for proper boiler care and operation. Sanitization Systems include temperature, time and the concentration of specific detergent solutions and bactericides. Cleaning and sanitizing procedures routinely include requirements at 121 degree's Celsius. Such factors as flavor control, homogenization, clarification, and separation of the product are also directly affected by temperature. The temperature control system typically uses an Indicating Thermometer to measure the process temperature. A second thermometer is used to limit the maximum temperature to a defined preset value. The temperature sensors are installed in a fitting at the outlet of the heating and or cooling system with and or without the use of a sanitary flange. These sensors have been mercury column thermometers in the past, but are now being replaced by high accuracy resistance temperature detectors (RTD's).

ANSI CALIBRATION Type J

Type J is composed of positive leg, which is iron and a negative leg, which is approximately 45% nickel-55% copper. When protected by compacted mineral insulation and appropriate outer sheath, Type J is useable from 32° to 1400°F. It is not susceptible to aging in the 700-1000°F temperature range, (+2°F to +4°F drift) which occurs with ANSI Type E and K. This low cost, stable calibraion is primarily used with 96% pure MgO insulation and a stainless steel sheath.

Type K

Type K is composed of a positive leg, which is approximately 90% nickel, 10% chromium and a negative leg, which is approximately 95% nickel, 2% aluminum, 2% manganese and 1% silicon. When protected by compacted mineral insulation and appropriate outer sheath, type K is useable from (-32° to 2300°F). If temperature range falls between (600° to 1100°F), we recommend using type J or N because of aging which can cause a drift rate of, (2°to 4° F) in a few hours time. For applications below (32°F), special selection of alloys are usually required.

Type N

Type N is composed of a positive leg which is approximately 14% chromium, 1.4% Silicon and 84.6% Nickel, a negative leg which is approximately 4.4% Silicon, 95.6% Nickel. When protected by compacted mineral insulation and appropriate outer sheath, Type N is useable from (32° to 2300°F). Type N was developed to overcome several problems inherent in Type K thermocouples. Aging in the (600° to 1100°F) temperatures is considerably less. Type N has also been found to be more stable than Type K in nuclear environments.

Type T

Type T is composed of a positive leg which is pure copper and a negative leg which is approximately 45 % nickel, 55 % copper. When protected by compacted mineral insulation and appropriate outer sheath, Type T is usable from (32° to 662°F). Type T is very stable and is used in a wide variety of cryogenic and low temperature applications. For applications below (32°F) special selection of alloys are usually required.

Type E

Type E is composed of a positive leg which is approximately 90% Nickel, 10% Chromium and a negative leg which is approximately 45% Nickel, 55% copper. When protected by compacted mineral insulation and appropriate outer sheath, Type E is usable from (32° to 1652°F). This Thermocouple has the highest EMF output per degree of all recognized thermocouples. If the temperature is between (600° to 1100°F), we recommend using type J or N because of aging which can cause drift of (2° to 4°F) in a few hours time. For applications below (32°F), special selection of alloys are usually required.

ANSI CALIBRATION Type S

Type S is composed of a positive leg, which is 90% platinum 10% Rhodium and a negative leg which is 100% Platinum. When protected by compacted mineral insulation and appropriate outer sheath, Type S is usable from ( 32° to 2700°F). Reducing atmospheres are particularly damaging and easily contaminated. Type S should be protected with gas tight ceramic tubes, a secondary tube of porcelain and silicon carbide or metal outer tubes as conditions require.

Type R

Type R is composed of a positive leg, which is 87% Platinum 13% Rhodium and a negative leg which is 100% Platinum. When protected by compacted mineral insulation and appropriate outer sheath, Type R is usable from (32° to 2700°F). Type R has a higher EMF output than type S. Also easily contaminated, and damaged by reducing atmospheres. Type R should by protected in a similar fashion as Type S.

Type B

Type B is composed of a positive leg which is approximately 70% Platinum, 30% Rhodium and a negative leg which is approximately 94% Platinum, 6% Rhodium. When protected by compacted mineral insulation and appropriate outer sheath, Type B is usable from, (1600° to 3100°F). Also easily contaminated, and damaged by reducing atmospheres. The same protective measures as shown above apply to type B Thermocouples.

Type C

Tungsten-5 % Rhodium/Tungsten-26 % Rhodium is generally referred to as type C. When protected by compacted mineral insulation and appropriate outer sheath, it is usable from, (32° to 4200°F). Used most often with Beryllium oxide insulation and either molybdenum or tantalum sheath. These combinations can only be used in an inert or vacuum environment.

MINERAL INSULATIONS HIGH PURITY MAGNESIUM OXIDE (MGO) 99.4% MINUMUM PURITY

Low impurity levels make this insulation very useful for all thermocouples calibrations up to 2500°F Hygroscopic , compacts well.

STANDARD PURITY MAGNESIUM OXIDE (MgO0 96% MINIMUM PURITY

This lower cost insulation is similar to high purity MgO except should not be used in applications above 2000°F because of the impurity levels. Should not be used with platinum or in nuclear applications.
